Area of Science:

  • Materials Science
  • Solid-State Chemistry
  • Optoelectronics

Background:

  • All-inorganic CsSnI3 is a promising near-infrared emitter.
  • Its structural stability is limited by a low tolerance factor, causing phase transitions in air.

Purpose of the Study:

  • To enhance the structural stability and air tolerance of CsSnI3 perovskite materials.
  • To develop stable near-infrared light-emitting diodes (LEDs) for practical applications.

Main Methods:

  • Developed a dual-ion substitution strategy by replacing Cs+ with guanidinium (GA+) and I- with thiocyanate (SCN-).
  • Investigated the structural and chemical mechanisms stabilizing the B-γ phase using component engineering.
  • Fabricated and characterized near-infrared LEDs incorporating the modified CsSnI3.

Main Results:

  • Optimized the tolerance factor (t) of CsSnI3, achieving stabilization of the B-γ phase for over 200 minutes in ambient air.
  • Demonstrated that SCN- suppresses Sn2+ oxidation and GA+ inhibits V_I formation through H-bonding.
  • Achieved a peak external quantum efficiency of 6.01% and an operating lifetime of 2500 minutes for the developed LEDs.

Conclusions:

  • Dual-ion substitution effectively enhances the air stability and performance of CsSnI3 near-infrared emitters.
  • The stabilized CsSnI3-based LEDs show potential for practical applications in night vision, medical imaging, and nondestructive testing.
